Plus 0/12dB switchable gain--total range 92dB.I surmise you do not own a Schiit preamp with 128 0.6dB volume steps.
It'd be easy to do more steps, and wider range, but one of our most typical comments is about "too much range" and "having to be high on the volume control" by people used to pots. There's 40dB more available at noon, not 10dB like many volume pots. People aren't used to that. I've considered skipping steps or going to fake log, the comments are that prevalent. But the right way to do it is how we're doing it.
Everything that goes to the speaker is analog. Even if it is a Class D approximation, linearized by feedback, smoothed by an output filter.We may be getting into semantics, but my understanding is that what's called a digital amp is typically a class D device that translates the incoming PCM into either pulse width modulation or pulse density modulation in the digital domain, and basically has one stage in the analog domain.
You can argue about DSP vs analog processing, but in the end, everything you hear is analog. Your ears aren't digital.
I personally wouldn't want an autoformer in the signal path—I'd prefer not to have the possible magnetic field sensitivity and reactive load. Heck, I really wouldn't want to worry about the frequency response of my volume control. That's super weird. But so am I, and maybe I'm crazy.The primary obstacle for transformer volume controls must be cost. The one you linked is for only a single channel and costs £185.33 (currently $235 USD), and each of the 24 taps still need to be wired into a quality selector switch. Double that for a stereo setup (dual mono). As I understand, a large part of the cost is that each attenuation tap must be individually calibrated. I see TVC passive preamps starting at $650 in kit form and running up to many thousands (for a passive preamp – just an input selector and volume control attenuator).
